A pair of these clutches drive vertically mounted brushes which scrub the sides of a vehicle in an automatic car wash. This clutch had to fill two requirements: (1) operate in an environment where exposure to both water and detergent is constant and (2) support the brush assembly. Below are the special features incorporated into this design:

Enclosed, sealed aluminum housing

Grease packed under top oil seal and inside the flange housing to prevent water seepage

Port in housing for vent tube. Ventilation prevents the clutch from acting as a pump and drawing water into itself during disengagement.
